Golub resents "that Warren Buffett and others who have created massive wealth for themselves think I'm 'coddled' because they believe they should pay more in taxes. I certainly don't feel 'coddled' because these various governments have not imposed a higher income tax. After all, I did earn it."

He also makes the case that the government has an obligation to show that it's spending "our tax money on programs that work" before asking anyone to pay more.

And Golub adds a point that other critics of the call for increasing taxes on the wealthy have been making in recent days:

"Almost half of all filers pay no income taxes at all. Clearly they earn less and should pay less. But they should pay something and have a stake in our government spending their money too."

Buffett's call for higher taxes on the wealthy largely echoes the position held by President Obama, who Buffett endorsed in 2008. The president has advocated letting the so-called Bush tax cuts expire for wealthier Americans.
